For anyone who was impressed with Jessamyn Duke’s UFC debut five months ago, Duke says you haven’t seen anything yet.

“I have improved tremendously since I’ve been out here,” the Kentucky native said of the several months she’s been training at Glendale Fighting Club. “I don’t even know if you can quantify it. I’m a totally different fighter for sure.”

The MMA world will see that different fighter Saturday, when Duke takes on Bethe Correia on the preliminary card at UFC 172 at the Baltimore Arena in Baltimore, Md.

THE FOUR HORSEWOMEN

After competing on “The Ultimate Fighter” and getting to know her coach, UFC women’s bantamweight champion Ronda Rousey, Duke accepted and invitation to live and train with Rousey along with Marina Shafir and fellow “TUF” and UFC fighter Shayna Baszler.

What’s more, Duke (3-0) has been able to train with Edmond Tarverdyan, who has a similar lanky build to the 5-foot-11 Duke.

Her progress under Tarverdyan’s watch has been as much mental as physical.

“He’s really polished what I’ve already had and brought out a lot of the strengths I didn’t even know I had,” the bantamweight said. “He’s really helped me develop some tools. Just really smart strategically. I go into the fight much more confident, a lot more relaxed. He’s helping me grow as a fighter.”

With just a few months at GFC under her belt, Duke made her UFC debut in November against fellow “TUF” competitor Peggy Morgan. Duke looked impressive in dominating Morgan for a unanimous-decision victory.

A second UFC victory would certainly move the 14th-ranked Duke up the rankings. In her way is 12th-ranked Correia (7-0), who in her UFC debut in December edged veteran Julie Kedzie by split decision.

“She’s nicknamed The Pitbull. I’m sure she’s gonna do the normal Brazilian thing and be very aggressive and in my face and try to mean-mug me, but I’ve got a great coach, a great team,” said Duke, who weighed in Friday at 135.5 pounds to Correia’s 135. “I’m feeling really good. I’ve already made huge improvements over my last fight. We watched the tapes and have already made adjustments.”

With Correia standing 5-5, Duke will have a 6-inch reach advantage, which will no doubt play into her striking strategy.
